Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the invention, fall within the scope of protection of the invention.
Unless defined otherwise, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The terms "first," "second," and the like, as used herein, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Likewise, the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate a relative positional relationship, which changes accordingly when the absolute position of the object to be described changes.
The present inventors have found that, first, the reason why the vacuum chuck 200 leaves suction marks on the surface of the adsorbate 2000 is that when the vacuum chuck 200 adsorbs the adsorbate 2000, only the center of the vacuum chuck 200 and the edge of the vacuum chuck 200 are closely pressed against the adsorbate 2000 by the adsorption force, and the adsorption force is too concentrated in the middle of the chuck 200, so that the center suction marks and the edge suction marks of the vacuum chuck 200 are easily left on the adsorbate 2000.
Secondly, the current vacuum chuck 200 is made of silica gel/rubber, which is easy to adhere to dust and dirt, and is easy to bring the dirt to the adsorbate 2000, and in use, the material is easy to fall off, and has large friction with the adsorbate 2000, and is frequently subjected to the action of adsorption force and friction force, so that the risk of abrasion and falling off is increased, and the material is remained on the adsorbate, so that the frequent replacement of the vacuum chuck 200 is very wasteful.
Based on the above findings, the present inventors have proposed a vacuum chuck pad 100, which is used on a vacuum chuck 200, and can effectively overcome the above problems.
Next, a vacuum chuck pad 100 according to an embodiment of the present invention will be described first.
Fig. 1 shows an alternative embodiment of a vacuum chuck pad 100 according to the present invention.
As shown in fig. 1, the vacuum chuck pad 100 according to the present invention includes a gas-permeable suction part 110, and the gas-permeable suction part 110 is used to cover the surface of the vacuum chuck 200.
In other words, the vacuum chuck 200 adsorbs the adsorbate 2000 by the ventilation adsorption part 110, and the ventilation adsorption part 110 is in full-face contact with the adsorbate 2000, so that the adsorption force is distributed uniformly, thereby realizing traceless adsorption, avoiding the risk that the adsorption force of the vacuum chuck 200 is concentrated in the middle of the vacuum chuck 200, so that the adsorbate 2000 is locally stressed too much, and the adsorbate 2000 is easily broken.
Further, the vacuum chuck pad 100 further includes a sleeve portion 120, and the sleeve portion 120 is formed in a cylindrical shape and one end thereof is connected to an edge of the air-permeable suction portion 110.
For example, the sleeve portion 120 and the air-permeable absorbing portion 110 are integrally formed, and the air-permeable absorbing material is formed in a shape (circular shape, square shape, etc.) larger than the area of the vacuum chuck 200, wherein the portion for contacting the bottom surface of the vacuum chuck 200 is the air-permeable absorbing portion 110, and the portion for wrapping around the vacuum chuck 200 is the sleeve portion 120.
Further, the other end of the sleeve portion 120 is provided with a receiving portion 130, and an elastic rubber ring or an extractable rope is arranged in the receiving portion 130.
In other words, the other end of the sleeve is closed by an elastic rubber ring or a drawable string (e.g., cinched and knotted by a drawable string).
In use, the sleeve portion 120 wraps around the vacuum chuck 200, and the closing portion 130 can make the vacuum chuck pad 100 closely contact with the chuck and is not easily detached even in a non-operating state (i.e., a vacuumized state).
When the vacuum chuck pad 100 needs to be replaced, the take-up part 130 can be opened (the elastic rubber ring is pulled open or the drawable rope is loosened), the vacuum chuck pad 100 is taken away from the surface of the vacuum chuck 200, and then a new vacuum chuck pad 100 is replaced, so that convenient replacement can be realized, and the cost of the vacuum chuck pad 100 is lower, and the cost can be saved.
According to other embodiments of the present invention, a bonding layer is disposed on one side surface of the breathable adsorption portion 110 along the edge of the breathable adsorption portion 110, and a release film is disposed on the bonding layer.
That is, the edge of the breathable adsorption part 110 is provided with an adhesive layer with a release film, and in the use process, the release film is torn off to attach the adhesive layer to the vacuum chuck 200, and the breathable adsorption part 110 is tightly combined with the vacuum chuck 200 by the adhesive force of the adhesive layer. Thus, a simple and convenient structure can be realized.
According to some embodiments of the present invention, the breathable adsorption portion 110 is formed with one or more through holes.
As shown in fig. 2, the breathable adsorption portion 110A is formed with 1 through hole, and the breathable adsorption portion 110B is formed with a plurality of through holes (for example, 10 through holes).
The through holes can increase the ventilation amount, thereby increasing the adsorption strength, so that the vacuum chuck pad 100 can adsorb the adsorbate 2000 more firmly, and can meet the use requirements of some adsorbates 2000 (such as heavy adsorbates 2000) with higher adsorption strength requirements.
Further, the breathable adsorption portion 110 is formed with a plurality of through holes, and the plurality of through holes are uniformly distributed in the breathable adsorption portion 110.
That is, the breathable adsorption portion 110 is formed with a plurality of through holes uniformly distributed in the breathable adsorption portion 110. Therefore, in the use process, the adsorption force can be uniformly distributed, and the adsorption strength can be increased.
According to some embodiments of the invention, at least the gas permeable suction portion 110 of the vacuum chuck pad 100 is formed of a fibrous material.
That is, the air-permeable adsorbing portion 110 of the vacuum chuck pad 100 is formed of a fibrous material, or both the air-permeable adsorbing portion 110 and the sleeve portion 120 are formed of a fibrous material.
The fiber material gas permeability is better, can make adsorption affinity distribution even, the vacuum chuck pad 100 that uses this material can adsorb adsorbate 2000 well, and the fiber material compliance is good, can avoid leaving the suction mark on adsorbate surface, and the fiber material can handle into dustless material (e.g. dustless cloth etc.), be difficult to adhere dust, can avoid leaving the dust on adsorbate 2000, simultaneously, the frictional force of fiber material and adsorbate 2000 is less relatively, and fiber material itself is difficult to drop, fiber material and adsorbate 2000 contact can not drop, the risk of remaining material itself at adsorbate 2000 has been avoided.
Further, the fibrous material may include one or more of nonwoven fabric, fibrous paper, knitted fabric, and the like.
According to some embodiments of the present invention, the breathable adsorption portion 110 includes a base layer having a hydrophobic and oleophobic layer formed on a surface thereof.
That is, the breathable adsorption portion 110 includes a base layer having a hydrophobic and oleophobic layer formed on a surface thereof.
Because of the hydrophobic and oleophobic properties of the substrate layer (e.g., nanolayer, etc.), during use, moisture and oil do not remain on the surface, so that the breathable adsorption portion 110 is cleaner, the adsorbate 2000 is adsorbed by the substrate layer, the surface of the adsorbate 2000 is less prone to leaving suction marks, the dust-free adsorption effect is enhanced, and the breathable adsorption portion can be used in high-humidity and greasy dirt environment.
In addition, the embodiment of the invention also provides a vacuum adsorption device 1000, which comprises a vacuum chuck 200 and a vacuum chuck pad 100.
The vacuum chuck pad 100 is any one of the vacuum chuck pads 100 described above.
For example, as shown in fig. 3, the vacuum suction device 1000 includes a vacuum chuck 200, a vacuum chuck pad 100, and a joint 300, one end of the joint 300 is used to connect to a suction pipe, the other end of the joint 300 is connected to the vacuum chuck 200, and the surface of the vacuum chuck 200 wraps the vacuum chuck pad 100.
As shown in fig. 4, in the use process, the vacuum adsorption device 1000 adsorbs the adsorbate 2000 (e.g., glass product), thereby realizing dust-free adsorption, improving the yield of the adsorbate 2000, and saving the cost.
The test comparative experiment group (vacuum suction device 1000 with vacuum chuck pad 100 according to the present invention) and the reference group (vacuum suction device commonly used in a direct use production line, that is, without vacuum chuck pad 100), each adsorb and transfer 50 pieces of mobile phone cover glass, and the result is shown in table 1 by observing whether suction marks remain under steam condition.
